I had purchased these in a size 32, and they fit fine at the waist, but are too tight in the legs (I'm a relatively slender guy, but I do ride bicycles and don't have skinny legs)- I needed to move up a size in order to be comfortable. The waist does have adjustable cinches, so any extra diameter can be pulled out.Also, pay close attention to the 360 zipper if you plan to use it. It was the opposite direction of my existing Joe Rocket jacket- I have to visit a tailor to see if I can get it reversed.
